Mach311 Posted January 5, 2006 Posted January 5, 2006 I think I have the all time worst overclocking Opteron 165 or I am doing something seriously wrong. My max stable overclock seems to be 2200Mhz 1.36v (245X9). No matter what voltage I give the processor it does not seem to want to budge over this speed. At 2200Mhz I am able to dual prime for 15hrs with load temps right around 37C. Here are my settings in bios: GENIE FSB 245 LDT: X 3.0 LDT Bus: 16 16 CPU Mult: X 9.0 PCI Exp : 100Mhz CnQ: Disable CPU VID Start: 1.45v CPU VID: 1.375v CPU VID Spec: 104% LDT Voltage: 1.3v Chipset Voltage: 1.7v DRAM Voltage: 2.9v DRAM +.03v: Disable DRAM Settings DRAM Freq: 100 CPC: 1T tCL: 3 tRCD: 3 tRAS: 8 tRP: 3 tRC: 7 tRFC: 13 tRRD: 2 tWR: 2 tWRT: 1 tRWT: 3 tREF: 3120 tWCL: 1 Bank Interleave: Enabled Skew Control: Auto Skew Value: 0 Drive Strength: Level 7 Drive Data Strength: Level 3 Max Async. Latency: 7ns DRAM Repsonse: Normal Read Preamble: 5.0ns Idle Cycle: 256 clks Dynamic Counter: Enable R/W Bypass: 16x Bypass Max: 7x 32-bit Gran.: Disable(4 burst) I got my settings from Here I have tried a bunch of different memory settings without any real improvement. One other thing that I have found a little unusual is that when I run prime over 2200Mhz it does not fail but rather hard crashes the computer. There is not a blue screen or anything it just completely restarts. I was previously using an Athlon64 3200+ Venice and never experienced any similar crashes. Any insight or suggestions would be greatly appreciated Quote Share this post Link to post Share on other sites More sharing options...
